BONDING AND TYING DEVICE.

SPECIFICATION forming part of Letters Patent No. 543,014, dated July 23,1 895.

Application filed April 19, 1895. Serial No. 546,357. (No model.)

To aZZ whom it may concern:

. Be it known that I, WILLIAM C. HANNA,Jr., a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and usefullmprovemcnts in Bonding and Tying Devices, of which the following is a specification.

forms of construction.

Anchor tie-rods as heretofore usually constructed have had their spear or pin so arranged with relation to the rod or bar that they become loose when in the hands of the workman, which is a great source of annoyance. Other constructions which provide against this contingency are expensive and cumbersome. The object of my invention is to overcome these objections, and to produce an article which is not only cheap, but durable and permanent in its structure.

A designates the rod or bar, having an opening B near its end. In Fig. 1 this opening is represented as being square, which is the preferred form, but the opening maybe made in any angular form, two of which forms are shown for the purposes'of illustration in Figs. 5 and 6. Through the openingB is passed the pin or spear O,its cross-section corresponding preferably to the shape of the opening.

When it has been passed through the opening to the desired extent, the spear is twisted both above and below the bar, thereby securely and permanently fastening it in place. This construction of the device is both simple and strong. No heating and weldingare necessary. The opening B is stamped out, and the pin or spear is easily twisted without the application of heat. As there are no welded joints, orin fact, no welding whatever about the device, the tensilestrength is much greater than in that class of anchors where such joints are employed.

The rod or bar A may be made in various forms, as necessary and desired.

In Fig. 2 my device is shown as a hookanchor, in Fig. 3 as a side anchor, and in Fig. 4 as a wall-anchor.

Having thus described my invention, what I claim is- As a new article of manufacture, a bonding or tying device comprising a rod or bar provided with an angular opening at one end, the opposite end being adapted to be secured to the structure in connection with which it is to be used; and a pin or spear passing through said angular opening,--said pin be-' WILLIAM G.
